A Close-Knit Effort

Volunteers from around the country are helping the American Heart Association (in connection with the Children’s Heart Foundation) celebrate American Heart Month. How? By knitting and crocheting adorable red hats for babies born in February at participating hospitals.

Little Hats, Big Hearts™, honors babies and moms in a very special way. These tiny red hats, on thousands of babies, symbolize our shared mission of heart-healthy lives for everyone. The effort also raises awareness of congenital heart defects, and what we can all do to help prevent them.

Did you know? Little Hats, Big Hearts™ started in Chicago in 2014. From just 300 little hats in the first year, the program has now embraced hundreds of thousands of babies, across more than 40 states.

How You Can Help

The response to Little Hats, Big Hearts™ has been amazing. We received more than 200,000 hats for distribution in 2018.

Check this page in the fall to learn how you can use your skills to help the littlest hearts, in celebration of American Heart Month the following February.
